Effect of Mn(II) incorporation on the transformation of ferrihydrite to goethite

A series of Mn-substituted goethites were obtained by the addition of Mn(II) to ferrihydrite in alkaline media, at different times. The total aging period was 24 h. Chemical analysis indicated that the Mn mol fraction (χMn) remained practically constant (ca. 8 mol%) in the oxalate-ammonium non-extra...
